The tonifying Qi branch pipe being separately connected.
9. based on the control method of the described in any item inflation facility multiple-unit central gas supply systems of claim 2-8, feature
It is: includes the steps that detection inflation facility internal pressure to control gas source unit and power pressure relief device working condition:
The step of detection inflation facility internal pressure is to control gas source unit and power pressure relief device working condition is as follows: internal
The pressure in pressure-detecting device real-time detection inflation facility inner inflatable region simultaneously sends a signal to control unit, fills when detecting
When the pressure Pi < P1 in gas facility inner inflatable region, control unit issues signal and controls gas source cell operation, gas source unit
It is supplied to intermediate buffering gas bag, and through blowdown pipe road direction inflation facility gas supply；
When detecting the pressure Pi > P2 in inflation facility inner inflatable region, control unit issues signal and controls gas source unit
It stops working；
When detecting the pressure Pi > P3 in inflation facility inner inflatable region, control unit issues signal control power pressure release dress
Work is set, inflation facility loses heart outward through power pressure relief device to be depressured；
When detecting the pressure Pi < P4 in inflation facility inner inflatable region, control unit issues signal control power pressure release dress
It sets and stops working；
P1, P2, P3, P4 are user's setting value, and P1 < P2≤P4 < P3.
10. the control method of inflation facility multiple-unit central gas supply system according to claim 9, it is characterised in that: also
Include the steps that detecting intermediate buffering gas bag internal pressure to assist control gas source cell operation state；
The step of detection intermediate buffering gas bag internal pressure is to assist control gas source cell operation state is as follows:
Gas bag pressure-detecting device real-time detection intermediate buffering gas bag internal pressure simultaneously sends a signal to control unit, when detecting
When inflating the pressure P0 < P5 in facility inner inflatable region, control unit issues signal and controls gas source unit high-frequency operation；
When detecting the pressure P0 > P5 in inflation facility inner inflatable region, control unit issues signal and controls gas source unit
Low frequency work.
